This exercise is an excellent way to develop rapid technique in the low register. I would suggest slurring everything. Slur everything and after you have fluidity in that approach then vary your articulations to add another layer of challenge.
This is a technical exercise for bassoon that emphasizes the lower register.
It’s a really great exercise to develop 2nd bassoon playing in an orchestra. There is a lot of left thumb work and this pattern can go all the way up to the highest register as well. You are executing this pattern using all of the keys.
The order of notes can also be shuffled around within a small intervalic space similar to the Hanon Piano exercises (a wonderful resource for developing technique). Simon Kovar’s Bassoon book is also an excellent resource.
